2면 밸란싱 기법을 이용한 드럼 세탁기 불평형 질량 예측

Abstract

In front loading washing machines, accurate estimation of unbalance mass is always required to achieve high speed spinning operations. This paper proposes an estimation method of unbalance mass including their magnitude and angular location in front loading washing machines using two plane influence coefficient method. An ADAMS dynamic analysis model of a front loading washing machine was developed and vibration experiment was conducted to estimate angular position of unbalance mass at each plane. Estimated results from analysis and experiment were verified by comparing the actual angular position of unbalance mass. This research shows that two plane influence coefficient method are appropriate to estimate an angular position of unbalance mass in front load washing machines.
